Erosion is the wearing away of the surface of the earth!Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations.

the process of eroding or being eroded by wind, water, or other natural agents

The gradual destruction or diminution of something: "the erosion of support for the party"

The wearing away of land or soil by the action of wind, water, or ice. In hydrologic terms, wearing away of the lands by running water, glaciers,winds, and waves, can be subdivided into three process: Corrasion, Corrosion, and Transportation. Weathering, although sometimes included here, is a distant process which does not imply removal of any material wearing away of rock or soil by the gradual detachment of soil or rock fragments by water, wind, ice, and other mechanical or chemical forces.the wearing away of the earth's surface by running water, wind, ice, or other geological agents; processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is removed from the earth's surface

An example of erosion is if let's say that there was a river on top of a mountain. As time passes by, the water will rub against the rocks and it will rub against …it so much that it will go through the rocks and then it will end up splitting through the mountain. An example of deposition is if let's say there is a river. As rocks and dirt fall into the water the river will carry the rocks and dirt down into an ocean or sea, and that will drop off the dirt somewhere else and so on.

Extreme environmentalists will hurt their cause by creating unreal pollution issues. There certainly are many, very valid, problems with pollution, including the rising use of… plastic bottles and chemicals we use every day. Pollution is a serious problem. Erosion can be man induced and can be a problem. When the two are added the issue become foolishness as pollution is not a cause of erosion. This is a sad political use of the term pollution.

rivers aren't permanently the same shape, through different methods rivers can be eroded and shaped over long periods of time. i will give four Hydraulic action, this is where… the sheer force of the water forces the river side to be eaten away, this can be through cracks in rock or mud which the water is forced into which can then break off fragments. Attrition, this is where large objects such as mud or rocks smash together and break of fragments. Abrasion, this is where particulates such as sand or small stones are carried by the river and rubbed on the river walls, this works much like sandpaper and grinds away the river corrosion, this is where chemical substances in the water that are particularly caustic react and dissolve river walls and other substances

Erosion prevention is the prevention of erosion, though this is probably not very helpful. Here are a few means by which you can prevent erosion: River: To prevent a meander …from moving, you would reinforce the outside bank, which would mean that you could not moveGlacial: Nothing, unless you increased global warming vastlyAeolian: Again, not a lotMarine: Build a sea wall, introduce wave breakers, or encourage the formation of a beach, or build an artificial reef.

Erosion caused by waves is known as Hydraulic Action, which mostly consists of air bubbles being forced into cracks in rocks. Waves also cause abrasion whereby material transp…orted in the wave collides at speed with a rock face, wearing it away. Wave erosion is a type of marine erosion.
